Susan's designs were at the forefront of contemporary style, and her 1972 design, Botanic Garden, became a worldwide best selling range of tableware. This range is still available for purchase from Portmeirion Online.

The success of Portmeirion Potteries was only one facet of Susan's life and work. Susan was an accomplished artist and author, drawing inspiration from the sea as did her father. Susan studied at Chelsea School of Art under Henry Moore and Graham Sutherland. Her paintings have been exhibited at the Festival of Britain and her many of the rooms at Portmeirion Village were furnished with her textile designs.

The pottery is now sold worldwide but its spiritual home is still here at Portmeirion.
